core.atomic.cas - multiple declarations
Function cas
Stores 'writeThis' to the memory referenced by 'here' if the value referenced by 'here' is equal to 'ifThis'. This operation is both lock-free and atomic.
bool cas(T, V1, V2)
(
shared(T)* here,
const V1 ifThis,
V2 writeThis
) pure nothrow @nogc @safe
if (!is(T == class) && !is(T U : U*) && __traits(compiles, ()
{
*here = writeThis;
}
));
bool cas(T, V1, V2)
(
shared(T)* here,
const shared(V1) ifThis,
shared(V2) writeThis
) pure nothrow @nogc @safe
if (is(T == class) && __traits(compiles, ()
{
*here = writeThis;
}
));
bool cas(T, V1, V2)
(
shared(T)* here,
const shared(V1)* ifThis,
shared(V2)* writeThis
) pure nothrow @nogc @safe
if (is(T U : U*) && __traits(compiles, ()
{
*here = writeThis;
}
));
Parameters
| Name | Description |
|---|---|
| here | The address of the destination variable. |
| writeThis | The value to store. |
| ifThis | The comparison value. |
Returns
true if the store occurred, false if not.
